Okay, here you see the elements of the array (@array) for one textblock (after using split). Now it should be easier to understand the rest of the script.

[0] NC_014171.1    
[1] RefSeq    
[2] gene    
[3] 14311    
[4] 14425    
[5]   .    
[6]  +    
[7]  .    
[8] ID=NC_014171.1:rrs_1;locus_tag=BMB171_C5091;db_xref=GeneID:9190898
new line but same 'textblock' of data

[0] NC_014171.1

[2] exon (oder CDS)

[6]  +

What I want is to create a hash: I want to extract the number behind the word 'GeneID' (line one of textblock, at the end of element 8) and this number should be the key of my hash. The values for my hash should first be stored in an array. I need the following information as values for my array: line one of textblock: $array 3 which is a number, $array 4 again a number, $ array 6 which is + or - line two of textblock $array 2 which can be the word 'CDS' or 'exon' So far the script is working. Problems arise when the next text block is processed.
